议论文是如何引出文章主旨的呢？对！议论文的特点就是开门见山，一般都会在文章开头就把文章的中心的论点写出来，这种写作方式也就是我们常说的：开门见山。开门见山中最常见的一种引出中心主旨的写作手法就是首段首句，也就是说文章第一段的第一句话就是我们要找的主旨句。下面给大家举一个例子感受一下：
France, which prides itself as the global innovator of fashion, has decided its fashion industry has lost an absolute right to define physical beauty for women. Its lawmakers gave preliminary approval last week to a law that would make it a crime to employ ultra-thin models on runways.
25. Which of the following may be the best title of the text?
[A] . The Great Threats to the Fashion Industry
[B] . Just Another Round of Struggle for Beauty
[C] . A Dilemma for the Starving Models in France
[D] . A Challenge to the Fashion Industry’s Body Ideals
上面的一段文字就是整篇文章的第一段，同学们注意到到加粗的黑体字了吗？加粗的句子就是我们要找的文章主旨句。这就是我们所说的议论文在首段首句引出文章主旨的一种方式。那么本题是一道主旨大意题，同学们看看根据我们所找的中心主旨句的意思选择哪个选项呢？对，首段首句的意思与D选项的意思相符合。通过这个例子，大家是不是也发现这个技巧真的很好用，那就快去运用到你平时做的主旨大意题中吧！
